12 Claims, N0 Drawings I,l-BRIDGED-BIS(N-ARALKYL-Z- AMINOETHANOLS) This application is a division of our copending application Ser. No. 123,096, filed Mar. 10, 1971.

This invention relates to compositions of matter classified in the art of organic chemistry as 1,1'-bridgedbis[N-(alkyl and/or aralkyl)-2-aminoethanols] and to a process for preparing them.

In its composition of matter aspect our invention provides l,1-(X)-bis[2-[(R-CH XR)amino]ethanol] of the formula wherein:

R, when taken alone, is hydrogen, alkyl of one to carbon atoms, cycloalkyl of four to seven ring carbon atoms, phenyl or phenyl substituted by one to three members selected from the group consisting of atertiary alkyl of one to four carbon atoms, hydroxy, atertiary alkoxy of one to four carbon atoms and halo or by a member selected from the group consisting of acetamido, dimethylamino, methylthio, methylsulfonyl, nitro, trifluoromethoxy and triflurormethyl;

R, when taken alone, is hydrogen or atertiary alkyl of one to four carbon atoms;

R and R, when taken together with CH N, are lpyrrolidinyl, piperidino, l-hexahydroazepinyl, morpholino or 4-methyl-l-piperazinyl;

X is a direct linkage, methylene or alkylene of two to 12 carbon atoms with bonds to the adjacent carbon atoms at different carbon atoms; and

acid-addition salts thereof.

The compounds of Formula I and acid-addition salts thereof have antibacterial activity in vitro and are useful as antibacterial agents.

In its process aspect our invention provides the process for preparing 1,1 '-(X)-bis[2-[(R- CH )(R')amino]ethanol] of Formula I which comprises condensing an amine of the formula RCH NHR' (Formula II) with a diepoxide of the formula claz cl-xlm (hr-n18. III),

wherein R and R of Formula II and X of Formula 111 have the same meanings ascribed thereto above in Formula I.

When R is alkyl of one to 15 carbon atoms, it is normal alkyl or branched alkyl as illustrated by methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, tertbutyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, and pentadecyl. Since R and the attached methylene are integral, they are named integrally when R is alkyl, phenyl and substituted phenyl. Thus the illustrated alkyls become, respectively, ethyl, propyl, butyl, isobutyl, pentyl, isopentyl, 2-methylbutyl, neopentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl and hexadecyl. When R and the attached methylene are phenyl or substituted phenyl, they are named as benzyl or substituted benzyl, respectively.

When R is cycloalkyl of four to seven ring carbon atoms, it is cyclobutyl, cyclopentyl, cyclohexyl or cycloheptyl.

When R is phenyl substituted by, or when R is, atertiary alkyl of one to four carbon atoms, it is methyl, ethyl, propyl, isopropyl, butyl, isobutyl or sec-butyl When R is phenyl substituted by atertiary alkoxy of one to four carbon atoms, atertiary alkoxy is methoxy, ethoxy, propoxy, isopropoxy, butoxy, isobutoxy or secbutoxy When R is phenyl substituted by halo. halo is fluoro, chloro, bromo or iodo.

-R (Formula I),

When X is alkylene of two to 12 carbon atoms with bonds to the adjacent carbon atoms at different carbon atoms, it can be unbranched or branched. If unbranched, X is l,2-ethylene, 1,3-propylene, 1,4- butylene, 1,5-pentylene, 1,6-hexylene, 1,7-heptylene, 1,8-octylene, 1,9-nonylene, 1,10-decylene, 1,1 1- undecylene, or 1,12-dodecylene. If branched, X is, for example, 1,2-propylene, 2,3-butylene, or 2,2-dimethyl- 1,4-butylene.

The manner and process of making and using the invention and the best mode of carrying it out will now be described so as to enable any person skilled in the art to which it pertains to make and use it.

The'preferred method for carrying out the process of condensing an amine of Formula II with a diepoxide of Formula III is the use of a solvent inert under the reaction conditions, for example, acetonitrile, benzene, chloroform, N,N-dimethylformamide, ethanol, methanol of tetrahydrofuran at a temperature in the range of 0 to 100 C. Methanol is the preferred solvent and room temperature is the preferred temperature.

Compounds of Formula I in which R is methyl are also prepared by methylating the corresponding compounds of Formula I in which R is hydrogen with formaldehyde and formic acid.

Formation of acid-addition salts of the compounds of Formula I is accomplished by standard methods with any pharmaceutically acceptable inorganic (mineral) or organic acid. If inorganic, the acid can be, for example, hydrochloric acid, hydrobromic acid, nitric acid,

- phosphoric acid or sulfamic acid. If organic, the acid can be, for example, acetic acid, glycolic acid, lactic acid, quinic acid, hydrocinnamic acid, succinic acid, tartaric acid, citric acid, methanesulfonic acid or benzenesulfonic acid.

That the acid be pharmaceutically acceptable means that the beneficial properties inherent in the free base not be vitiated by side effects ascribable to the anions.

Although pharmaceutically acceptable salts are preferred, all acid-addition salts are within the scope of the invention. A pharmaceutically unacceptable salt may be useful, for example, for purposes of identification or purification or in preparing a pharmaceutically acceptable salt by ionrexchange procedures.

The intermediate amines of Formula II are a known class of compounds, whose preparation is accomplished by any of several well-known methods. The amines in which R is hydrogen, alkyl or cycloalkyl can be prepared, for example, by reductive amination of the corresponding aldehyde, by amination of the corresponding halide or alcohol p-toluenesulfonate ester or by reduction of the corresponding nitrile, oxime, am-

ide, azide or other higher-oxidation-state nitrogen compound. The amines in which R is phenyl or substitutedphenyl can be prepared, for example, by brominating the corresponding toluene, treating the resulting a-bromotoluene with hexamethylenetetramine and treating the resulting product successively with sulfur dioxide hydrochloric acid and ammonia; by reductive amination of the corresponding aldehyde or by reduction of the corresponding nitrile, oxime, amide or other higher-oxidation-state nitrogen compound.

The intermediate diepoxides of Formula III are also a known class of compounds. Their preparation is accomplished by epoxidation of the corresponding dienes by any of several well-known methods, for example, by the use of peracetic acid buffered with sodium acetate.

The compounds of Formula I and acid-addition salts thereof are purified by recrystallization. Their structures follow from their route of synthesis and are corroborated by infrared spectral analysis and by the correspondence of calculated and found values of elemental analysis of representative samples.

As stated above the compounds of Formula I have antibacterial activity in vitro, which was determined by a standard serial dilution test. In this test the concentration of compound arresting the growth of the microorganism is-the bacteriostatic concentration and is expressed in parts per million (p.p.m.).- The concentration of compound preventing growth of the microorganism after further incubation isthe bactericidal concentration and is also expressed in parts per million.

The compounds of Formula I and acid-addition salts thereof are useful as antibacterial agents and are especially useful for disinfecting and sanitizing living and non-living surfaces by conventional swabbing, padding, spraying, immersing, rinsing and the like techniques. Depending on the particular purpose involved, the compounds are used in aqueous solution, in aqueous detergent solutions or in solutions in organic solvents.

The following examples illustrate specific embodiments of our invention without limiting the latter thereto.
